The bag valve mask (BVM) offers accurate, dependable operation coupled with the ability to manually feel a patient’s respiratory response, all in a tamper-proof package for single patient use. Every BVM comes with a bag, patient valve, and 7 feet of oxygen tubing. Most child and all infant bags come with a pop-off relief valve, which pops off at 45 cm H20 max and can be overridden by the operator. When specific repeatable concentrations of oxygen are required, the bag refill valve can be employed in conjunction with a blender. When used as oxygen supplemented source, this device also ensures high FIO2 concentrations on every bag compression — no matter which clinical rate is employed. It will also conserve gas in the process by operating only while the bag refills.

The bag valve mask is designed to be utilized with supplimental oxygen but this does not mean that the device can not function without an oxygen source. Without supplimental oxygen the overall percentage of oxygen delivered is greatly reduced.
